Over the past 40 years of satellite observation, Antarctic sea ice defied global warming predictions and gained impressively. The mean temperature of the southern ice cap also shows no warming.
In 2017, after decades of inconvenient rise, sea ice extent suddenly fell to record low level and panic activity among global warming alarmists began to perk up. Surely the days of a growing Antarctic ice cap were over – at least they hoped.
But since 2017, the ice has grown back and once again has reached near normal levels and the long-term trend continues to be upward:

Schneefan just posted that latest May Antarctic sea ice extent. The data show that minimum 15% sea ice concentration coverage has climbed to a 5-year high for this time of the year:

So the Antarctic long-term trend for sea ice continues to be robustly upward.
No warming
One aspect that is supposed to indicate global warming is a rapid warming at the poles. But here too there has been no evidence of warming over Antarctica:
Global warming alarmists likely are going to have to wait a long time before they can begin dreaming about sounding the climate alarms over Antarctica. Things there are going the opposite way.
